There is provided magnetizing apparatus and magnetizing method for a magnetized pulser ring, by which magnetic force to which a cylindrical elastic magnetic member (2) is magnetized can be enhanced, and yet in which centering of a magnetizing yoke (3) is easy to achieve. A magnetizing portion (3a) of the magnetizing yoke (3) is a conical surface (3a) slightly tilted with respect to an axis thereof. The magnetizing yoke (3) is inserted into a cylindrical steel plate (1) of the magnetized pulser ring (10) so that the magnetizing portion (3a) of the magnetizing yoke (3) is brought into close contact with one axial end portion (2b) of the cylindrical elastic magnetic member (2). <IMAGE> |
